Cutting is the first step in your sample preparation, if you need a manageable size of the sample material. The aim of cutting is to obtain a surface that is plane, with a minimum of mechanical deformation and thermal damage. Our Aka-Cut cut-off wheels are optimised for different materials to obtain the best and most uniform cutting result every time. When you select the correct cut-off wheel, you can reduce time and cost for subsequent grinding and polishing.

Cutting of Metals
Abrasive cutting wheels are used for cutting metals with a hardness of 50-1000 HV. Our cut-off wheels provide a low cost per cut because they are long-lasting and cut fast. They are optimised to provide a plane cut with a minimum of thermal damage and maximum reproducibility. When cutting steel and/or other hard metals, the cut-off wheels Aka-Cut Fe60 or Aka-Cut Fe50 are the perfect choice. Aka-Cut 500 HV is optimised for ferrous metals with a hardness of approximately 250-500 HV and surface hardened steels to limit pinching and breakage of the cut-off wheel. Aka-Cut Ti20 is ideal for titanium and titanium alloys preventing overheating and smearing. Aka-Cut NF10 is the perfect choice for non-ferrous metals, like aluminium, copper and their alloys.
Precision cut-off wheels Aka-Cut Fe60, Aka-Cut Fe40 and Aka-Cut NF10 are the optimal choices for high precision cutting because they are very thin, yet durable. Our precision cut-off wheels are available in 150 mm dia.

What is the difference between Al2O3 and SiC cut-off wheels?
Al2O3 cut-off wheels are typically used for ferrous metals and SiC wheels for non-ferrous metals.
Are different abrasives used for cutting materials with different hardness?
Usually the same abrasive, e.g. Al2O3 is used for the same material group. There can of course be different types of Al2O3 and also different grain sizes, but in most cases it is the binder that is modified to suit the material to be cut. A soft binder, releasing grains faster, assures that the abrasives are always sharp when cutting hard materials, and a hard binder keeps the grains for a longer time and thus increases the lifetime of the cut-off wheel when cutting softer materials.
